2.2.4. Direct to Factory Pin Support for Remote System Update (RSU) Feature

Intel® Stratix® 10 SoC supports the Remote System Update (RSU) feature. When you use this feature, you have the option to store multiple production images alongside a failsafe factory image on the external SDM flash. Upon exiting POR, SDM attempts to load the production images in your specific sequence. If all the production images fail to load, then the failsafe factory image is loaded.

GUIDELINE: Use the Direct to Factory Image pin to instruct the SDM to load either Factory or Application Image when exiting POR.

The Direct to Factory Image is an optional pin that can be used with the RSU feature.1 If this pin is asserted during POR, the SDM does not attempt to load any production image; instead, the SDM loads the Factory Image directly from the external SDM flash.

For more information about using the HPS together with the RSU feature, refer to the Intel® Stratix® 10 SoC Remote System Update (RSU) User Guide.

1 Both factory and application images are stored in the SDM flash.
